Although the external electrode of multi-layer ceramic capacitor (MLCC) is formed through the burning process after coating the liquid state of Ag paste on the base material of the dielectric ceramics, there is an issue that the coating shape of the film thickness of the external electrode is not uniform enough by the influence of the surface tension. However, there are various changes occurred at the phenomenon by providing the ultrasonic vibration to the liquid, and therefore, it can be projected that it becomes to be similar to the ideal coating shape of this Ag paste. In this study, we thought that the coating shape becomes better by controlling the surface tension which is obtained by adding the ultrasonic vibration at the Ag paste coating to the laminated chip condenser and aimed to verify it by the experiment. As a result, we could find the beginning which controls the surface tension and improves the coating shape, by controlling ultrasonic vibration.
